wherein at least the actuator of the device for adjusting the Aufgabepunktes with a program-technically established control unit is in operative connection.

Distributing machines of the aforementioned type are known on the one hand in the form of agricultural spreading machines for discharging powdery or particulate material, in particular fertilizer or seed, in a variety of configurations, such as drawn or from a three-point of a tractor, such as a tractor, recorded design. Such distributing machines comprise a container receiving the material to be distributed, on whose underside usually one or two outlet openings are arranged, wherein the respective outlet opening is associated with a metering device to the auszubringende Good in the desired amount - or more precisely: with the desired mass flow - the container refer to. The usually positioned below the outlet opening metering is usually by means of a suitable actuator up and zuusteuerbar to depending on the desired distribution width of the material to be delivered on the ground, depending on speed and depending on the physical properties of the material to be spread, such as its flowability, the to be able to set the desired mass flow. Below the metering device is a distributor, by means of which the powdered or particulate material is distributed over the desired working width. Some distribution machines are also equipped with a device for adjusting the point of delivery of the powdery and / or particulate material on the, in particular from one equipped with throwing blades Distributor formed, distributing organ equipped, the task point with respect to the distributor member radially (in particular to increase / decrease the spreading fan) and / or in the circumferential direction (in particular for rotating the spreading fan about the axis of rotation of the distributor member) can be adjusted. In this case, the device for adjusting the application point usually has one or more actuators, which are used for reciprocating the dosing part equipped with the metering device of the metering device relative to the distributor - and thus also relative to the generally stationary with respect to the container arranged outflow opening is formed, said reciprocating motion, as mentioned above, may be a translational and / or a rotational movement. The control or regulation of the actuator of the device for adjusting the task point as a function of the desired distribution width takes over a programmatically set up control unit of the distributor, which usually with at least one operating module in operative connection, which may be arranged for example in the cab of a tractor, such as a tractor. The same applies generally for the control or regulation of the dosing depending on the desired mass flow of the material to be spread.

Such agricultural distribution machine is for example from the DE 41 34 315 A1 known. In this distributor in the form of a two-disc spreader, the container has two container parts, which taper downwards in a funnel-shaped manner. At the bottom of the container parts they are open, so that they each end in an approximately circular outlet opening. Below each outlet opening of the container parts is a metering device attached to the underside of the container parts such that an approximately cup-shaped metering part, which is equipped with a cooperating with a metering metering, can be rotated by a means for adjusting the task point of the material to be spread on the distributor disks about a vertical axis, so that the Dosing with the eccentric arranged to the rotation axis metering relative to the distributor member and relative to the opposite larger outlet opening at the respective bottom of the container parts can be rotated and the grit can thus be given a changed peripheral region on the distributor discs. An agitator is arranged above each outlet opening of the container and mounted on a fixed in the interior of the container linkage.

A likewise formed in the form of a two-disc spreader agricultural distributor of the above type is also for example the DE 10 2007 053 550 A1 refer to. It differs from the distributor according to the DE 41 34 315 A1 primarily by the geometry on the one hand the outlet opening, on the other hand, the metering device. The former is provided in a bottom fixed to the bottom of each container part and thus extends only over a part of the cross section of the respective, downwardly tapered container part. Below the bottom of the container provided with the outlet opening, in turn, the metering device is arranged, which in this case comprises an approximately plate-shaped metering part which is equipped with a metering opening cooperating with a metering slide. Similar to the above DE 41 34 315 A1 serves a device for adjusting the task point of the material to be spread on the distributor discs for rotating the - here plate-shaped - metering about a vertical axis, so that the metering can be rotated with its eccentric to the rotational axis metering relative to the distributor and relative to the opposite larger outlet opening along the direction of extension in the respective bottom of the container parts and the grit Consequently, a changed circumferential range can be applied to the distribution discs. At the not provided with the outlet opening portion of the container bottom, a stirrer is mounted.

In the case of winter service spreading machines, the container is primarily used for receiving granulated chips and / or road salt, the function of such a winter service spreading machine largely corresponding to that of an agricultural spreading machine described above.

For environmental reasons, and in particular for minimizing the amount of material to be disposed of, such as mineral fertilizer or road salt, at the agricultural or municipal depot, there is a need, according to the spreader in the container remaining remnants of grit either on site, ie in the field or To spread as completely as possible on the road or to collect such remnants of grit on the agricultural or municipal depot and returned to corresponding storage containers, such as warehouses or silos. In this context, it should be noted that in particular generic distribution machines for agricultural use often have containers with a capacity of several 1000 1, with not inconsiderable amounts of litter remains at the bottom of the container can remain. The removal of such scraps in the As part of a container cleaning it has hitherto required, for example, go over a hinged to the container ladder into the container to sweep the grit, for example by means of a broom or the like from the container. This is on the one hand relatively complex and uncomfortable, on the other hand, this can certainly represent a not insignificant accident risk. In that regard, be on the DE 20 2008 013 948 U1 directed.

The aforementioned DE 10 2005 015 228 A1 addresses this problem in part by the special geometry of equipped with the agitator outlet opening of the container bottom in conjunction with the provided below the outlet opening, provided with the metering, plate-shaped metering of the metering device, wherein it is provided that the equipped with the outlet opening bottom at the bottom of the Container having an approximately "V" -shaped circumference with rounded "V" crest, wherein the radius of curvature of the "V" crest approximately congruent with the circle of action of the agitator of the agitator and the outlet opening in the "V" crest opposite, extended Area of the "V" -shaped bottom is arranged. The agitator is thus able to promote in the region of the "V" crest left over scattering material in the direction of the outlet opening, resulting in a reduction of the remaining residual amount of grit, if the grit to fall through the located with a portion of the outlet opening in the dosing of the metering part can. However, even in such an embodiment, residual quantities of material to be spread which are not negligible remain in the container, which accumulate in particular on the upper side of the metering part of the metering device facing the container or its outlet opening, and in particular under Influence of moisture, as it is practically always present during use in the field, may be present in the form of aggregations and adhesions of more or less large lumps, especially since many types of grit, such as mineral fertilizer or road salt, have a more or less strongly hygroscopic character.

The invention is therefore based on the object, a distribution machine of the type mentioned in a simple and cost-effective way to the effect that at least largely avoided the aforementioned disadvantages, the remaining after the scattering work in the container residual amount of grit is reduced as much as possible.

• wenn die Steuereinheit einen entsprechenden, in ein Bedienmodul der Steuereinheit eingegebenen Befehl empfängt; und/oder
• wenn eine mit der Steuereinheit in Wirkverbindung stehende Füllstandserfassungs- und/oder Massenstromerfassungseinrichtung detektiert hat, dass der Behälter entleert worden ist und/oder bei geöffnetem Dosierschieber ein allenfalls kleiner oder kein Massenstrom an Streugut die Dosieröffnung durchsetzt.

According to the invention, this object is achieved in a distributor of the type mentioned above in that the control unit causes the actuator of the device for adjusting the application point to at least one to-and-fro movement around the metering equipped with the metering between two different positions relative to the outlet opening to shift back and forth,

• when the control unit receives a corresponding command input to an operation module of the control unit; and or
• if a level detection and / or mass flow detection device operatively connected to the control unit has detected that the container has been emptied and / or if there is an open metering slide, at most a small or no mass flow of grit passes through the metering opening.

The invention therefore provides that, on the one hand, if necessary, the control unit causes the actuator of the device for adjusting the delivery point to be moved at least once to a command entered into the operating module, which, for example, may emptying "residual amount" or the like. such that the dosing part of the dosing device provided with the dosing opening is displaced back and forth between two different positions relative to the outlet opening on the underside of the container which is larger in relation to the dosing opening and the dosing opening is thus moved over at least part of the outlet opening (or more precisely: approximately parallel to the plane of extent of the outlet opening below the same) in order to allow residual amounts of spreading material located there to fall out of the container through the dosing opening of the dosing part displaced back and forth. In this way, not only an effective residual emptying of located on the located below the outlet opening of the container metering of the metering device remaining scattered material, but the embodiment of the invention also proves to be extremely simple and inexpensive, since the already existing device for adjusting the task point "misappropriated" can be used, so that in order to implement the invention basically only a corresponding program-technical modification of the control unit is required.

On the other hand, alternatively or in addition to the demand-based activation of the emptying of residue according to the invention by an instruction entered into an operating module of the control unit, it may be provided that emptying of residues is carried out automatically, ie the control unit initiates the actuator of the device for adjusting the dispensing point to at least one to-and-fro movement to reciprocate the metering member equipped with the metering orifice between two different positions relative to the discharge orifice when a level detection and / or mass flow sensing means operatively connected to the control unit has detected that the container has been emptied and / or with open dosing a possibly mininaler or no mass flow of grit passes through the metering. As described below, such fill level and mass flow detection devices generic distribution machines are known in various configurations.

• Behälterwaage;
• Drehmomentsensor, welcher das Drehmoment wenigstens einer Welle im Antriebsstrang des Verteilorgans erfasst;
• Torsionssensor, welcher die Torsion wenigstens einer Welle im Antriebsstrang des Verteilorgans erfasst;
• Drucksensor, welcher den Druck in einem hydraulischen Antriebsstrang eines hydraulischen Antriebs des Verteilorgans erfasst; und
• Strom- oder Spannungssensor, welcher die Stromstärke oder die Spannung an einem elektrischen Antrieb des Verteilorgans erfasst,

gewählt ist. Bei der Füllstandserfassungseinrichtung kann es sich demnach einerseits um eine Behälterwaage handeln, welche mit der Steuereinheit in Wirkverbindung steht, so dass letztere des erfindungsgemäßen Restmengenentleervorgang veranlasst, sobald sie erkannt hat, dass die Behälterwaage einen leeren Behälter detektiert hat. Derartige Behälterwaagen sind bekannt und können zum Einen als lediglich statische Füllstandsanzeigen dienen, oder sie können einen Teil des Regelkreises des Dosiervorgangs in Abhängigkeit der Arbeitsbreite, der Fahrtgeschwindigkeit und insbesondere der physikalischen Eigenschaften des Streugutes bilden, wie es beispielsweise aus den EP 0 537 857 B1 , EP 0 674 831 B1 oder EP 0 982 571 B1 bekannt ist. Andererseits kann die Massenstromerfassungseinrichtung einen oder mehrere Drehmoment- und/oder Torsionssensor(en) umfassen, welche(r) das Drehmoment wenigstens einer Welle im Antriebsstrang des Verteilorgans erfasst/erfassen, wobei derartige Sensoren einen unbelasteten Zustand des Verteilorgans erkennen können (wenn der Behälter leer ist, gelangt kein oder nur noch sehr wenig Streugut durch die offene Dosieröffnung hindurch auf das Verteilorgan; das Drehmoment nimmt folglich mehr oder minder schlagartig ab) und gleichfalls mit der Steuereinheit in Wirkverbindung stehen. Derartige Sensoren können gleichfalls einen Teil des Regelkreises des Dosiervorgangs in Abhängigkeit der Arbeitsbreite, der Fahrtgeschwindigkeit und insbesondere der physikalischen Eigenschaften des Streugutes bilden, wie es beispielsweise aus der EP 1 008 288 B1 , EP 0 963 690 A1 oder aus der zum Prioritätstag der vorliegenden Anmeldung noch nicht veröffentlichten DE 10 2012 002 585.8 bekannt ist. Sofern das/die Verteilorgan(e) einen hydraulischen Antrieb mit einem oder mehreren Hydromotoren aufweist/aufweisen, ist es überdies denkbar, dass die Massenstromerfassungseinrichtung einen oder mehrere Drucksensor(en) umfasst, welche(r) den Druck in einem hydraulischen Antriebsstrang eines hydraulischen Antriebs des Verteilorgans erfasst/erfassen, wobei z.B. ein Drucksensor stromauf und ein Drucksensor stromab des Hydromotors angeordnet ist. Derartige Drucksensoren vermögen in ähnlicher Weise wie die vorgenannten Drehmoment- oder Torsionssensoren einen unbelasteten Zustand des Verteilorgans zu erkennen (wenn der Behälter leer ist, gelangt kein oder nur sehr wenig Streugut durch die geöffnete Dosieröffnung hindurch auf das Verteilorgan; der Druckverlust in dem hydraulischen Antriebsstrang nimmt folglich mehr oder minder schlagartig ab), wobei sie gleichfalls mit der Steuereinheit in Wirkverbindung stehen können. Auch sie können einen Teil des Regelkreises des Dosiervorgangs in Abhängigkeit der Arbeitsbreite, der Fahrtgeschwindigkeit und insbesondere der physikalischen Eigenschaften des Streugutes bilden, wie es beispielsweise aus der DE 44 17 549 C2 , EP 0 945 548 A2 oder EP 0 963 690 A1 bekannt ist. Entsprechendes gilt für Strom- oder Spannungssensoren, welche die Stromstärke oder die Spannung an einem elektrischen Antrieb des Verteilorgans erfassen, wobei die Stromstärke und/oder die Spannung eines solchen elektrischen Antriebs gleichfalls für das durch den Massenstrom an auftreffendem Streugut auf das Verteilorgan bewirkte Drehmoment des Verteilorgans repräsentativ sind. Darüber hinaus sind auch andere, z.B. optische, Ultraschall-, elektromagnetische Sensoren oder dergleichen, denkbar, welche den Abwurfbereich erfassen, in welchem die Streugutpartikel üblicherweise die Verteilorgane verlassen. Derartige Sensoren sind beispielsweise aus der DE 197 23 359 A1 bekannt.Thus, it can be provided in an advantageous embodiment that the fill level and / or mass flow detection device from the group

• Hopper scale;
• A torque sensor which detects the torque of at least one shaft in the drive train of the distributor;
• Torsion sensor, which detects the torsion of at least one shaft in the drive train of the distributor;
• Pressure sensor which detects the pressure in a hydraulic drive train of a hydraulic drive of the distributor member; and
• Current or voltage sensor which detects the current intensity or the voltage at an electrical drive of the distributor,

is selected. Accordingly, the level detection device can on the one hand be a container scale, which is in operative connection with the control unit, so that the latter causes the residue emptying process according to the invention as soon as it has detected that the container balance has detected an empty container. Such container scales are known and can on the one hand serve as merely static level indicators, or they can form part of the control loop of the metering process depending on the working width, the travel speed and in particular the physical properties of the material to be spread, as for example from EP 0 537 857 B1 . EP 0 674 831 B1 or EP 0 982 571 B1 is known. On the other hand, the mass flow sensing device may include one or more torque and / or torsion sensors that detect the torque of at least one shaft in the driveline of the distributor, such sensors being capable of detecting an unloaded state of the distributor (when the container is empty is, no or very little grit passes through the open metering opening on the distributor, the torque decreases more or less abruptly) and also be in operative connection with the control unit. Such sensors can also form part of the control loop of the dosing process as a function of the working width, the travel speed and in particular the physical properties of the material to be spread, as for example from the EP 1 008 288 B1 . EP 0 963 690 A1 or from the date of priority of the present application not yet published DE 10 2012 002 585.8 is known. If the distributor (s) has / have a hydraulic drive with one or more hydraulic motors, it is also conceivable for the mass flow detection device to comprise one or more pressure sensors which determine the pressure in a hydraulic drive train of a hydraulic drive of the distributor member detected / detected, for example, a pressure sensor upstream and a pressure sensor is arranged downstream of the hydraulic motor. Such pressure sensors are able to operate in a manner similar to the abovementioned torque sensors. or torsion sensors to detect an unloaded state of the distributor (when the container is empty, no or very little grit passes through the open metering opening on the distributor, the pressure drop in the hydraulic drive train decreases more or less abruptly), and it also can be in operative connection with the control unit. They too can form part of the control loop of the metering process as a function of the working width, the travel speed and in particular the physical properties of the material to be spread, as can be seen for example from US Pat DE 44 17 549 C2 . EP 0 945 548 A2 or EP 0 963 690 A1 is known. The same applies to current or voltage sensors which detect the current intensity or the voltage at an electrical drive of the distributor, wherein the current intensity and / or the voltage of such an electric drive also for the mass flow of impinging on the distributor member caused torque of the distributor are representative. In addition, other, for example, optical, ultrasonic, electromagnetic sensors or the like, are conceivable, which detect the discharge area in which the grit particles usually leave the distribution organs. Such sensors are for example from the DE 197 23 359 A1 known.

If the distribution machine has such a fill level and / or mass flow detection device and the control unit comprises an adjustment module into which a corresponding command can be entered to command the residual emptying process, it may also be expedient for the control unit to suppress the residue evacuation process or at least before causes them to generate a warning, eg visual and / or audible, when it receives such a command, but the level and / or mass flow detection device detects at least one at least partially filled container.

In an advantageous embodiment can be provided that the control unit causes the actuator of the device for adjusting the task point (as mentioned above, if necessary and / or automatically) to a multiple, in particular at least two, preferably at least three times, reciprocating to the with the metering equipped dispensing part several times between the two different positions back and forth. The associated with the actuator, provided with the metering dosing of the metering device can thus be repeatedly moved back and forth between two positions to a corresponding control command of the control unit, so that relatively strongly adhering or baked residues of grit aggregates can be mechanically solved by the back and forth moving dosing be removed.

In an expedient embodiment, the control unit causes the actuator of the device for adjusting the task point to an at least one-off reciprocating movement between two stop positions of the same to move the metering equipped with the metering dosing between two end positions back and forth. In this case, the metering device of the metering device provided with the metering device is moved back and forth over the largest possible range of its displaceability along the underside of the container provided with the outlet opening in order to also deposit on the edge side To be able to discharge residues of particles through the dosing opening from the container.

As mentioned at the outset, the actuation of the dosing part equipped with the metering orifice can be a translational movement and / or preferably a rotational movement, in particular a substantially vertical axis of rotation, depending on the mounting thereof. can coincide with the axis of rotation of the distributor.

According to an advantageous development of the invention, it can be provided that the control unit further sets an agitator associated with the outlet opening in the interior of the container in rotation when it causes the actuator of the device for adjusting the task point to the at least unique reciprocating movement. Due to the command entered into the operating module of the control unit and / or due to the empty state of the container detected by the level detection device, the control unit consequently also causes the agitator located inside the container to be used as such with regard to correct flow of the material to be spread during the spreading work generic distribution machines is in use (see, for example, the cited above DE 10 2007 053 550 A1 or DE 10 2005 015 228 A1 ) is put into operation. Any remnants of spreading material located in the vicinity of the outlet opening and / or the metering opening of the metering unit which can not sweep the metering opening of the metering unit on the occasion of its displacement according to the invention can thus be moved in the direction of the outlet opening on the underside of the container by means of the agitator and to the back and forth "wandering" dosing be promoted of the metering, so that even those deposited in hard to reach place residual amounts of grit can be removed from the container.

While the agitator basically can of course also circulate about an axis that is approximately horizontal or inclined with respect to horizontal at a finite angle, it may be advantageous if the agitator has a substantially vertical axis of rotation, in particular coaxial with the axis of rotation of the distributor element ,

If the metering device is in operative connection with the control unit, as in the generic distribution machine for controlling or regulating the mass flow of grit depending on the desired working width, the driving speed and / or the physical properties of the material to be spread, in particular its flowability, usually the Case is, it is expedient if the control unit further causes a drive of the metering slide to transfer the metering slide in an open position in which it substantially completely releases the metering opening of the metering part, in particular, when the actuator of the device for adjusting the Aufgabepunktes ( if necessary and / or automatically) to the at least one-off reciprocation causes. Alternatively, of course, a e.g. Manual transfer of the metering slide carried out in its open position before or during the Restmengenentleervorgang invention is performed.

In a preferred embodiment it can be provided that the metering opening over at least 60%, in particular over at least 80%, preferably more than 90%, for example, by substantially 100% of the distance between the opposite edges of the outlet opening at the bottom of the container extends transversely to the displacement path of the dosing provided with the metering. As a result of the control technology caused actuator displacement back and forth of the metering provided with the metering portion (or "underlines") the metering consequently covers at least a majority, preferably the entire surface of the opposite larger outlet opening to remaining on the metering or fallen down thereon residues almost completely out of the container at the spreading material.

In order to provide a simple and convenient input of the control command for starting the emptying process according to the invention as required, the control module of the control unit may, for example, have a menu point directed to a complete residue emptying of the container, which allows the input of the corresponding command. A corresponding input device of the operating module may be of conventional design and e.g. a keyboard, a touch screen, a voice input system or the like.

According to one embodiment, it may be provided that the control unit further stops a drive of the distribution member associated with the outlet opening, for example a scattering or distribution disc, if it causes the actuator of the device for adjusting the task point, if necessary, to the at least one to-and-fro movement. In this way, a more or less wide distribution of the discharged residual amount of grit in prevent the environment, which is particularly advantageous if the remaining quantity to be recorded and reused.

According to another embodiment, it can be provided that the control unit further comprises a drive of the distribution member associated with the outlet opening, e.g. a scattering or distribution disc, activated when it causes the actuator of the device for adjusting the task point, if necessary, to the at least one-time reciprocating motion. In this way, the discharged residual amount of spreading material can be distributed in a simple manner at the location of the scattering work, for example in a field or on the road.

In the latter case, it may also be advantageous if the control unit further generates a message when it causes the actuator of the device for adjusting the task point when activated drive of the distributor, if necessary, to the at least one-way back and forth, the message in particular on a display the control module is displayed and / or played back acoustically. Such a message, which may be mutatis mutandis "Caution - Dosierorgan in operation" or the like, serves primarily to warn the user that due to high ejection speed of the spreading device accelerated residues of grit during the Restmengenentleervorgangs invention there is a risk of injury when he is in Stops near the moving distribution organs.

In order to take into account both of the abovementioned variants, the operating module can preferably provide an input, which enables the selection of whether the drive of the distributor member in the demand, at least one-off reciprocation of the actuator of the device for adjusting the task point to be shut down or activated, the control unit depending on the selection entered the drive of the distributor shutdown or activated ,

The actuator of the device for adjusting the delivery point which is connected to the metering part of the metering device can be formed, for example, by a hydraulic, pneumatic, hydropneumatic or, in particular, electric actuating cylinder, as known from the prior art.

• den Aktuator einer jeden Einrichtung zur Verstellung des Aufgabepunktes oder
• einen den Einrichtungen zur Verstellung des Aufgabepunktes gemeinsamen Aktuator

zu einer wenigstens einmaligen Hin- und Herbewegung veranlasst, um die mit den Dosieröffnungen ausgestatteten Dosierteile aller Auslauföffnungen zwischen zwei verschiedenen Positionen hin und her zu verlagern,

• wenn die Steuereinheit den entsprechenden, in ihr Bedienmodul eingegebenen Befehl empfängt; und/oder
• wenn die mit der Steuereinheit in Wirkverbindung stehende Füllstands- und/oder Massenstromerfassungseinrichtung detektiert hat, dass der Behälter entleert worden ist und/oder bei geöffnetem Dosierschieber ein allenfalls minimaler oder kein Massenstrom an Streugut die Dosieröffnung durchsetzt.

Of course, as already indicated, the distributor according to the invention need not only one, but may also have several, in particular two, outlet openings, metering devices, devices for adjusting the delivery point and distribution elements, the control unit in particular

• the actuator of each device for adjusting the task point or
• a common to the means for adjusting the task point actuator

causes at least one to-and-fro movement to displace the metering orifices of all the discharge ports between two different positions equipped with the metering orifices,

• when the control unit receives the corresponding command entered in its control module; and or
• when the fill and / or mass flow detection device operatively connected to the control unit detects has that the container has been emptied and / or with open metering a possibly minimal or no mass flow of grit passes through the metering.

If such a distribution machine, as usual, also has two containers or a container with two separate container parts, it may be appropriate, at least when the control unit comprises an actuator common to the devices for adjusting the task point, if this actuator only to the Reciprocation is caused when both containers (parts) have been completely emptied in order not to affect the spreading operation of the still (partially) filled container (part) s.

In addition, it is of course expedient in terms of the most complete emptying of residual material of the grit container when the container (or the container or the container chambers one and the same container) tapers in the direction of the outlet opening is substantially funnel-shaped or tapered.

Moreover, it has the beginning in connection with the DE 10 2005 015 228 A1 mentioned reasons, when a arranged at the bottom of the container, provided with the outlet opening bottom of the container has a substantially "V" -shaped circumference with rounded "V" crest, wherein the radius of curvature of the "V" crest about is arranged congruent with the active circle of the agitator of the agitator, wherein the outlet opening in a "V" crest opposite, extended region of the "V" -shaped bottom is arranged. The rounded "V" -crest of the container bottom can hereby preferably approximately concentric to the axis of rotation of the - to rotate about a vertical axis of rotation - be arranged agitator.

In Fig. 1 is an embodiment of a distributor according to the invention in the form of a two-disc spreader designed as agricultural spreader reproduced by way of example. The distribution machine has a frame 1 with a cross-beam 2, which, for example, in the case of one of the PTO of a tractor, such as a tractor derived mechanical drive of the distribution discs formed in the form of distribution devices 3, 4, which are provided with throwing blades 5, 6, takes a transverse drive. In the case of a speed-controllable, hydraulic or electric drive, for example, the hydraulic or electric motors associated with each distributor 3, 4 are connected to the cross-beam 2.

The distributor further comprises a container 7, which is equipped in the present case with two funnel-shaped container parts 8, 9, which taper downwardly in a substantially funnel shape and merge at their lower sides, for example, each in a polygonal shaped lower part 10, 11, each with an outlet opening. The latter is configured in the present embodiment, for example annular and eccentrically arranged in a surrounding this bottom 12, 13 (see. Fig. 2 to 6 ). How the particular Fig. 2 can be seen further, below the annular, the outlet openings of the container 7 limiting bottoms 12, 13 each provided a metering device, each one, in the manner explained below by means of (ever) a device for adjusting the task point of the material to be spread on the distribution organs 3, 4 actuatorally movable back and forth metering 14, 15 with a metering 16, 17 whose free cross-section is controlled by means of a, in particular actuators actuated likewise, metering slide 18 for adjusting the spread rate.

How out Fig. 2 Furthermore, it can be seen that the outlet opening of each container part 8, 9 of the container 7 is associated with an immediately above each bottom 12, 13 arranged agitator 19, which in the following Fig. 3 and 4 has been omitted for illustrative purposes and its vertical axis of rotation 23, 24 with that of the distributing members 3, 4 (see Fig. 1 ) coincides. The axis of rotation 23, 24 of the agitator 8, for example, stored in the respective bottom 12, 13 and be rotationally driven by a otherwise not shown, controllable drive, as he eg as such from the DE 10 2005 015 228 A1 is known. The arrangement of the agitators 19 is selected such that the space below the arranged in the respective bottom 12, 13 outlet opening on the one hand and the associated distributor member 3, 4 on the other hand remains free, so that the fertilizer can reach the distributor member 3, 4 disability-free. In this way, the distribution members or distributor disks 3, 4 (FIG. Fig. 1 ) with the ends of their throwing blades 5, 6 ( Fig. 1 ) The grit in each case from a scattering fan, which partially overlap and give a flat triangular scattering pattern. During the connection, this results in a linear distribution. The one distributor 3, 4 throws the grit to about half the working width on the other side, so that a border spreading is possible. However, the present invention can be in any other type of a single or double disc spreader implement for agricultural or winter service purposes.

The polygonal, for example, octagonal, designed lower part 10, 11 passes at its lower edge in the annular, the outlet opening limiting bottom 12, 13, above which the agitator 19 rotates with substantially radially extending stirring fingers 20 about the rotation axis 23, 24. Each bottom 12, 13 has an approximately "V" shaped circumference with a rounded "V" vertex 13a, which in the present case is relatively strongly rounded by a corresponding radius of curvature, the center of the radius of curvature of the "V" vertex 13a on the axis of rotation 23, 24 of the agitator 19 is located. The above-mentioned in the radial direction of the rotation axis 23, 24 of a respective agitator 19 above agitating finger 20 or its active circle coincides approximately with the radius of curvature of the "V" crest 13a of the bottom 12, 13 together. At the part-circular "V" -crest 13a of the bottom 12, 13 opposite side of the bottom 12, 13 also has a circular arc-shaped termination 13b. The radius of this arcuate portion 13b is appreciably larger than the radius of curvature of the "V" crest 13a. Both are interconnected by approximately linear sections which form the "V" legs of the "V" shaped bottom perimeter. As already mentioned, the annular bottom 12, 13 defines the large-area outlet opening, which is arranged eccentrically in the region of the bottom 12, 13 which is opposite the "arcuate" section 13b and which has a circular arc-shaped section Diameter (in Fig. 2 left) and a likewise arcuate section of contrast smaller diameter (in Fig. 2 right) as well as these connecting, approximately linear Has sections. The outlet opening delimited in this way by the annular bottom 12, 13 preferably occupies more than 50% of the total area of the floor 12, 13.

The metering slide 18 is in Fig. 2 hatched for clarity. The metering opening 16, 17 of the metering part 14, 15 extends in particular over virtually the entire distance between the in Fig. 2 left, the agitator 19 facing away from the edge and the right, the agitator 19 facing edge of the outlet opening in the arranged on the container bottom bottom 12, 13 transversely to the displacement P of the metering 14, 15. The centrally arranged inside edge of the metering 16, 17 may be asymmetric formed wavy, which ensures that in conjunction with the adjustable from inside to outside dosing slide 18 results in a favorable distribution even at low mass flows. The agitator fingers 20 of the agitator 19 pass over the metering opening 16, 17 only in the area of small mass flows, ie in the area of the inner, wavy edge of the metering opening 16, 17. The remaining area of the metering opening 16, 17 for large mass flows, as well as the outwardly disposed region of the outlet opening are not detected by the stirring fingers 20.

Again Fig. 3 can be seen, can be moved to move the by the position of the metering openings 16, 17 of the metering parts 14, 15 with their metering slides 18 (see Fig. 2 ) certain task points on the distributor members 3, 4, the metering parts 14, 15 about its center of rotation 23, 24 twist. This purpose is served by a device provided overall with the reference numeral 25 for adjusting the delivery point, which in the case of Fig. 2 each comprises an actuator 26, 27, for example in the form of an electric actuating cylinder, and a mounted on a center console 28 lever linkage. The actuators 26, 27 and the center console 28 are arranged offset between the distributing members 3, 4 or between the distributor disks and with respect thereto or on the vertical axes of rotation 23, 24 of the metering parts 14, 15 of the metering devices in the direction of travel 22 to the front. The example formed by electric cylinders actuators 26, 27 are supported at one end to a respective fixed console 29, 30 and how Fig. 4 can recognize, arranged horizontally one above the other.

At the in Fig. 3 and 4 reproduced embodiment engages an actuator 31, 32 of each actuator 26, 27 on a pivot lever 33, 35a of the lever linkage, which act at the other end to a rotatably mounted in the center console 28 pins 35, 35a. The latter is connected at its opposite end in each case with a pivot lever 36, 37, the pivoting movement via a joint 39, 40 on each one, outwardly extending handlebar 41, 42 is transferable, which in turn articulated at each one of the reciprocally rotatable metering plates 15, 16 of the metering devices acts. The in Fig. 4 Upper actuator 26 acts via its actuator 31 and the lever linkage 33, 37 with the pivot 35 and the handlebar 41 with its hinge 43 on the in Fig. 3 and 4 Dosing part 14 shown on the left (right dosing plate 14 in the direction of travel 22), while the lower actuator 27 acts on the dosing part 15 reproduced on the right in the drawing via the analog lever of the lever linkage.

In addition, it can be provided that with each reciprocating metering part 14, 15 a position indicator 45, 46, e.g. in the form of a pointer, which cooperates with a container-fixed scale 47, 48. The scales 47, 48 are provided with a scale representing the position of the task point.

In the Fig. 5 and 6 identical or functionally identical components are provided with the same reference numerals. In the Fig. 5 and 6 reproduced embodiment of the device 25 for adjusting the task point differs from the according to Fig. 3 and 4 in that it comprises only a single actuator 49, again designed, for example, in the form of an actuating cylinder, in particular an electric actuator, which serves for the rotational reciprocating movement of the metering parts 14, 15 of both metering devices at the same time. The actuator 49 acts with its actuator 50 on the connected to the rotatable in the center console 28 pin 35a pivot lever 34. On the rotatable pin 35a sits in turn the pivot lever 38 which engages at point 40 articulated to the handlebar 42, which in turn via its joint 44 the in Fig. 5 and 6 right dosing part 15 adjusted. In that regard, the device corresponds to 25 for Adjustment of the task point with the actuator 49 and the lever linkage that part of the device 25 according to Fig. 3 and 4 with the actuator 27 and the parts of the lever linkage moved by its actuating element 32 (the same reference numerals for the lever linkage have therefore been adopted). Notwithstanding the embodiment according to Fig. 3 and 4 However, here are the two pivot levers 34 and 51, of which latter the handlebar 41 for the back and forth rotatable (in Fig. 5 and 6 left) metering part 14 drives, via a coupling 52 connected to each other, which is formed in the embodiment shown by two intermeshing Stirnradsegmenten 53, 54. The spur gear segments 53, 54 each sit on the pivot pins 35, 36, so that they join in their rotational movement and provide synchronous operation of the actuation path of the actuator 49 initiated pivotal movement of the pivot lever 34, 51 and the travel of the handlebars 41, 42.

The two different positions are in particular to the end positions of the metering parts 14, 15, which is predetermined by the reciprocation of the actuators 25, 26 and 49 between its two stop positions, so that the metering port 16, 17 of the respective metering part 14, 15 practically the entire surface of the Outlet opening in the direction of arrow P according to Fig. 2 repeatedly submerged, so that any, deposited thereon Soreugutreste can be removed through the open metering opening 16, 17. For this purpose, the control unit at the same time causes the drive of the metering slides 18 to transfer them into their maximum open position, in which they release the metering opening 16, 17 of the respective metering part 14, 15 entirely. In addition, the control unit also sets the agitators 19 in rotation, so that residual quantities of spreading material which are located at the side of the agitator 19 which is opposite the outlet opening are narrow (see FIG Fig. 2 right of the agitator 19), are promoted by the agitator fingers 20 in the direction of the outlet opening and due to reciprocally rotated back and forth dosing parts 14, 15 entirely through the metering opening 16, 17 from the respective container part 8, 9 can be removed.

The control module of the control unit may further preferably be an input possible, which allows the operator, if he wants to carry out the aforementioned residue emptying process as needed, a selection of whether the drive of the distributing organs 3, 4 should be shut down or activated during the residue emptying process, so that the control unit depending on the selection entered the drive of the distributing organs 3, 4 can activate or shut down. The options can be displayed, for example, on a display device of the operating module are and mutatis mutandis, "block distribution disks" or "activate distribution disks", wherein the operator can enter the desired selection by pressing a button, clicking or the like. In the case of a selection entered in its operating module, according to which the distributing elements 3, 4 are to be activated, the control unit is able to generate in particular an optical and / or acoustic warning message in order to warn the operator of a risk of injury during the thawing of the remaining grit particles, if he during the remainder of the emptying process in the vicinity of the distributing organs 3, 4 resides.
